Abstract
A modular retaining wall comprising a plurality of tie-back units with a plurality of retaining wall panels therebetween. Each tie-back element is shaped substantially similar to each retaining wall panel. Each element comprises a main body with a cored cavity, a neck at each end of said main body, and a column attached to each neck. Each neck on the tie-back element has opposing concave surfaces for mating with the convex surface of each column of the soil-retaining element.

Structure for a modular assembly for retaining soil, comprising in combination at least a pair of laterally spaced tie-back elements, each tie-back element comprising,
- a first wall,
- a second wall,
- a first end portion connecting said first and second walls;
- a second end portion connecting said first and second walls,
- said first and second walls and said first and second end portions forming a first cored cavity therebetween,
- each said first and second end portions comprising
- a first column end, and
- a first neck connecting said first column end to said first and second walls,
- a soil-retaining panel spanning such lateral space between each said pair of tie-back elements, each said retaining panel comprising:
- a third wall,
- a fourth wall,
- a third end portion connecting said third and fourth walls,
- a fourth end portion connecting said third and fourth walls,
- said third and fourth walls and said third and fourth end portions
- forming a second cored cavity therebetween,
- each said third and fourth end portions comprising:
- a second column end, and
- a second neck connecting said second column end to said third and
- fourth walls, and
- wherein said first neck of said tie-back comprises opposing concave outer surfaces, and wherein each said second column of said soil-retaining panel comprises a convex outer surface for mating with said concave neck surfaces of said laterally spaced tie-back elements.
